Used in the North of England particularly Liverpool and Merseyside, meaning delighted, happy about something, over the moon!
Though it can also be used as a sarcastic retort.
"When i found out i'd got the job, I was made up!" Or "her face lit up when she opened her present, you could tell she was really made up with it."
The sarcastic retort usage of the term, would be something like, when someone was jealous of someone. The person might say: "Hey i got a date with that fella! and you would reply, "I'm made up for ya!" (when really you were no such thing)
